Person to copy European-style bread sandwiches (4,5)
I believe the answer is:
role model
'person to copy' is the definition.
(someone setting an example to be followed)
'european-style bread sandwiches' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'style' becomes 'mode' (synonyms).
'bread' becomes 'roll' (roll is a kind of bread).
'sandwiches' is an insertion indicator (to sandwich is to block something in).
'e'+'mode'='emode'
'emode' put into 'roll' is 'ROLE-MODEL'.
(Other definitions for role model that I've seen before include "good person" , "someone to look up to" , "example for kids" , "someone worthy of imitation" , "exemplary type" .)
